PROGRAMMABLE BLANKING FOR ASYNCHRONOUS DRIVER BREAK
The invention concerns a converter circuit for providing a load current to a load, in particular to a lighting device such as a LED lighting module. The converter circuit comprises at least one switch configured to switch between a conducting state and a non-conducting state based on a switch control signal. A current sense circuit of the converter circuit generates a current sense signal based on a sensed current via the switch. Based on the current sense signal, a control circuit of the converter circuit generates the switch control signal. The control circuit controls the switch to switch asynchronously from the conducting state to the non-conducting state when the current sense signal reaches a threshold value. The converter circuit is characterized by the control circuit setting a blanking time interval, wherein the blanking time interval starts at a time when the switch switches from the non-conducting state to the conducting state, and, during the blanking time interval, the control circuit inhibits switching the switch from the conducting state to the non-conducting state.
